FILTER AND TRAP.

Application filed February To chf colto/'1t 'it 11u03/ concern:

Be it known that l, .loi-1N S. Carsten, a citizen ot the United States, residing at larsou, in the county of lottawattamie and State of lowa, have invented new and uselul improvements in Filters and Traps, of which the :following is a specilication.

This invention relates to a filter and trap for liltering the gasoline supply ot motor vehicles and the like, and Vwhich may be used for other purposes, the `general object of the invention beirng;V to provide a chamber with the filtering medium at the top thereof so that sediment and water will collect in the bottom ot the chamberI where it can be easily removed and will not clog up the liltering medium or the pipes of the. device.

Vifinother object ot the invention is to provide the device with a window so that the passage oit the fluid through the same can be seen.

This invention also consists in certain other features of construction and in the combinationI and arrangement ot the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specilically pointed out in the appended claim.

In describing my invention in detail, reterence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which r- Figure 1 is a sectional view through the device.

Figure 2 Figure 1.

Figure 3 Figure 1.

' Figure l Figure 1.

In these views, 1 indicates a base member of substantially saucer shape and which has connected thereto!w the lower end of a cylinder 2 which is provided with elongated openings t in its lower part and with an internal flange 5 at its upper end. The base is also provided with an annular groove 6 which 's spaced outwardlyT 'from' the cylinder' 2. A drain cock 7 is arranged at the center ot the base so that the de vice can be drained by opening this cock. A. top meinber- 8 is provided with a cup-shaped recess 9 at its center, the walls of which are screw threaded to receive the screw threaded upper end is a'section on line 22 of is a section on line 3-3 of is a section on line 1 -4 of 13, 1925. serrer ne. aero.

ot the cylinder' 2 and the outer part olf this member provided with an annular groove l0. A cylinder 11, ot glass or other transparent material, has its upper and lower edges engaging the `grooves 6 and 10, suitable packing material 12 being placed in the grooves to malte a water tight joint bctween the parts. A metal jacket 18 encloses the cylinder l1 to protect the same and this 'iaclret is provided with a window 1-1 which exposes a portion ot the cylinder so that the interior of the device can be seen through said window. ri screen 15 or other 'filtering .medium is placed on the flange 5 and held in place by a ringl lo which. is threaded in the end of the cylinder 2. An outletnipple 1T is in con'nnunication with the recess 9 and an inlet port 18 is formed in the member 3 and is in communication with the space between the cylinders 2 and 11.

From the foregoing it will be seen that the incoming Vfluid flowing into the device through the port 18 will be directed towards the bottom of the. saine by the closed upper part ot the cylinder 2. This fluid will pass through the openings l and continue upwardly through the screen 15 into the recess 9 and pass out ot the nipples 17.. Foreign matter and water in the 'Huid will collect in the bottom of the device, as shown in Figure 1 and this matter can be drained by openingthe cock T. The foreign matter will not interfere with the passage of the fluid through the device and as it does not come in contact with the screen it will not clog the screen. The device can be easily cleaned by removing the base part without interfering with the pipe connections or the member 8. l

The parts are assembled by lirst. placing the screen 15 in the cylinder 2 and screwingin the ring` 16. Then the cylinder 11 and the jacket 13 are placed with their lower ends in the groove of the base and then the top member 8 is screwed upon the top of the cylinder 2 until its groove engages the top ot the glass cylinder and jacket. The parts are screwed down tight enough to make a tight joint between the gaskets 12 and their contacting parts. i

It is thought from the foregoing descrip tion that the advantages and novel features oi my invention will be readily apparent.

l desire it to be understood that l may malte changes in the construction and in the combination and arrangement of the several parts', provided that such changes fall Within the scope of the appended Claim.

IVhat I claim is A device of the class described comprising a base having a drain opening, a cylinder connected at its lower end with the base and forming a central chamber, a second cylinder surrounding and spaced from the first and forming an outer chamber, a top member Connected with the inneil cylinder, and

with the top end of the outer cylinder, the top lneinber having an inlet passage therein communicating with the top of the other chamber and an outlet passage communicatin` with the top of the inner chamber, a screen adjacent the top of the inner chainber, the inner cylinder having elongated openings in its bottoni part and a Window in the outer Cylinder.

In testimony whereof I affix my signature JOHN S. CRISLER.
